This design resulted from the need for a replacement of the drop sensor in an old vending machine which is no longer in production and therefore hardly obtainable. The replacement is a homemade module ...

This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

Chibitronics combines familiar adhesive stickers with bits of LEDs, sensor circuits, and even a programmable microcontroller, to create a playful set that educates while adding some flash to one ...

New Sensor Bares Faults In Smallest Possible, Most Advanced Circuits Date: May 12, 2003 Source: Brown University Summary: A new scanning microscope developed at Brown University can uncover ...

Finger sensor circuit diagram showing sensing traces (33), drive/shield electrodes (35) and switches (42, 43).

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials.

The researchers designed an electronic health monitoring system that consisted of sensor circuits printed directly on the back of a human hand, as well as a paper-based FPCB attached to the inside ...
